Hello mobizt

Arduino IDE Version 1.8.19
Board : ESP32 Dev module
Flash size : 8mb
Partition scheme : 3Mb App / 1.5 spiffs
Board Manager version Esp32 : 2.0.5
Library version 2.7.0

webserver and email library, Is it possible run together?
when email is sending and I am on webserver setting some configuration.
this situation can cause unstable/error the connection email server or not?
if this can make unstable connection to the email server. could you please give me advices.

thank you so much.

If your device connected to the network that can access the internet, you can access to the mail server as normally while your device provides the web server functionality.

Running email task in CPU core 1 is ok. I'm not sure for core 0, you can test with lower priority task.
